A circle is centered at O. The tangent to the circle at P is extended to Q. Line segment QS intersects the circle at R Given that OS = 2 , SR = RQ = 3 and , PQ = 8, find the radius of the circle.
The radius of the circle is 2*sqrt(10).
PQ cannot be 8 !!!
..........................................
PQ = 6
Radius = √22
